A Study of Market Segmentation and Positioning on Industrial Furnace System Integration from A Global Perspective

Lee, Jui-Kuo 28 June 2002 (has links)
Industrial furnace is very important production equipment for industrial enterprises. Its performance will directly affect the efficiency and effectiveness of enterprises in manufacturing industry, even change the competitive advantage of the organization. To achieve more high quality and synergy, there is a need to have an integrated industrial furnace system that may compose of industrial furnaces, network, computer automatic control, intelligent software, and decision support technical. The integrated industrial furnace system takes the place of the traditionally single and dummy industrial furnace gradually. The importance of the integrated industrial furnace system to the enterprise is increased dramatically. With the change of market focus from production-orientation to customer-orientation, more and more companies realize the importance of the strategy of market segment and position. ¡§The small market segment¡¨ and ¡§unease of standardization¡¨ (high customization) are major characteristics in the industrial furnace industry. Therefore, the market and position strategy is the critical successful factor for the furnace industry in addition to technical excellence. Taiwanese industrial furnace companies are becoming global business recently. This research will focus on exploring the market and position strategy of furnace industry from a global perspective. This research will combine qualitative and quantitative methods. First, we will adopt literature review, in-depth interview, and focus-group interview with suppliers, customers, scholars, market analysts, and economic officials to develop two measure instruments: the supplier strategy measure and customer preference and selection criterion measure. Second, we will survey via questionnaires, and test reliabilities and validities of the both measures conscientiously. Finally, we formally mail validated questionnaires to suppliers and customers in the industrial furnaces industry. Based on multivariate analysis, factor analysis, cluster analysis, and multi-dimensional scaling, we will provide insights and suggestion about integrated industrial furnace system industry: 1.The strategy patterns of industrial furnace suppliers 2.The selection criterion of industrial furnace in a broad customer perspective 3.The grouping of customers and supplier in the integrated industrial furnace system industry. 4.The perceptual map of major suppliers in the integrated industrial furnace system industry 5.The strategy, market segment, and position current analysis and future suggestions

A MCDM Method for Selecting an ERP System

Tai, Wei-Chun 12 July 2002 (has links)
In this e-commerce era, Enterprise Resource Planning (ERP) has been viewed as the entering cost for conducting the business and establishing contact with others. ERP system is very expensive and enormous complex package software, and applies the best business practice with partial adjustment and integration to suit for the operation of different enterprises. But due to the characteristics of high investement, high complexity and high risk of failure of ERP systems, misfits have been one of important issues for the implementation of ERP systems. Therefore, the selection of an appropriate ERP system has become the key factor leading to the eventual success of an ERP system implementation. And we select an appropriate ERP system by studing a case that uses ELECTRE I as evaluating tool. This paper first identifies a set of evaluating criteria based on the extensive literature review and the considerat5ion of the environment and characteristics of ERP systems. Once the list was generated, an iterative process of personal interview with the consultant, suppliers, users and managers was conducted to modify the evaluating criteria in order to insure the integrity of it. The result of this study is not only can contribute to the understanding of the functionalities of an ERP system, but also can provide a practical guideline for the selection of an ERP system.

Distributed Multi-path Routing with QoS Support in Wireless Ad Hoc Networks

Huang, Yi-Xiang 19 July 2002 (has links)
In an ad hoc networks, it is an important problem about how to increase the bandwidth utilization and guarantee Quality-of-Service. In order to increase the bandwidth utilization under the situation of limited bandwidth, we want to achieve the target by using the bitty residual bandwidth in the ad hoc networks. Hence we integrate several single paths into a multi-path that satisfies QoS requirement. In this paper, we present a policy to look up, maintain, and reroute the virtual circuit in the ad hoc networks. From the result of simulation, we obtain that our proposal indeed can increase the bandwidth utilization of ad hoc networks. But the condition of splitting also increases the overhead of connection, and affects the forced terminated ratio and packets lost ratio under mobility.

The Relationship Between the Product Stategies of Multi-Level Maketing Company With the Distributors

Chou, Chin-Jung 09 August 2002 (has links)
As we know that the process of visions, strategies, plans, actions, reviews and re-plans are essential to managing a company and strategies obviously are the main guideline of all. The product strategies in marketing are recognized as the starting point to various kinds of strategies in production, marketing, human resource, R&D, finance, information system and logistic¡Ketc. The distribution organization of Multi-Level Marketing companies (hereafter named ¡§MLM companies¡¨) is different from those of other industries because in addition to being a customer, the distributors are not only their sales representatives but also supervisors of the sales teams. Therefore, the characteristics of distribution organization must be particularly taken into account while MLM companies plan on their product strategies. If they know well about the characteristics, the products strategies can be successfully initiated and company goal can be easily achieved as a result. In this study the data was collected through questionnaires which focus on the following three main issues in order to compare the differences and similarities of consideration factors between MLM companies and distributors while MLM companies plan on their product strategies.

Multi-area power system state estimation utilizing boundary measurements and phasor measurement units ( PMUs)

Freeman, Matthew A 30 October 2006 (has links)
The objective of this thesis is to prove the validity of a multi-area state estimator and investigate the advantages it provides over a serial state estimator. This is done utilizing the IEEE 118 Bus Test System as a sample system. This thesis investigates the benefits that stem from utilizing a multi-area state estimator instead of a serial state estimator. These benefits are largely in the form of increased accuracy and decreased processing time. First, the theory behind power system state estimation is explained for a simple serial estimator. Then the thesis shows how conventional measurements and newer, more accurate PMU measurements work within the framework of weighted least squares estimation. Next, the multi-area state estimator is examined closely and the additional measurements provided by PMUs are used to increase accuracy and computational efficiency. Finally, the multi-area state estimator is tested for accuracy, its ability to detect bad data, and computation time.

A multi-exchange heuristic for formation of balanced disjoint rings

Sasi Kumar, Sarath K 30 October 2006 (has links)
Telecommunication networks form an integral part of life. Avoiding failures on these networks is always not possible. Designing network structures that survive these failures have become important in ensuring the reliability of these network structures. With the introduction of SONET (Synchronous Optical Network) technology, rings have become the preferred survivable network structure. This network configuration has a set of disjoint rings (each node being a part of single ring), and these disjoint rings are connected via another main ring. In this research, we present a mathematical model for the design of such disjoint rings with node number balance criterion among the rings. When, given a set of nodes and distances between them, the Balanced Disjoint Rings (BDR) problem is the minimum total link length clustering of nodes into a given number of disjoint rings in such a way that there is almost the same number of nodes in each ring. The BDR problem is a class of the standard Traveling Salesman Problem (TSP). It is clear from this observation that the BDR problem becomes a TSP when the number of rings required is set to one. Hence BDR is NP-Hard, and we do not expect to obtain a polynomial time algorithm for its solution. To overcome this problem, we developed a set of construction heuristics (Break-MST, Distance Method, Hybrid Method, GRASP-Based Distance Method) and improvement heuristics (Multi-Exchange, Single Move). Different combinations of construction and improvement heuristics were implemented and the quality of solution thus obtained was compared to the standard Branch and Cut Technique. It was found that the algorithm with GRASP-Based Distance Method as the construction heuristic and multi-exchange - single-move combination as the improvement heuristic performed better than other combinations. All combinations performed better in general than the standard Branch and Cut technique in terms of solution time.

Improvements in communication complexity using quantum entanglement

Kamat, Angad Mohandas 10 October 2008 (has links)
Quantum computing resources have been known to provide speed-ups in computational complexity in many algorithms. The impact of these resources in communication, however, has not attracted much attention. We investigate the impact of quantum entanglement on communication complexity. We provide a positive result, by presenting a class of multi-party communication problems wherein the presence of a suitable quantum entanglement lowers the classical communication complexity. We show that, in evaluating certains function whose parameters are distributed among various parties, the presence of prior entanglement can help in reducing the required communication. We also present an outline of realizing the required entanglement through optical photon quantum computing. We also suggest the possible impact of our results on network information flow problems, by showing an instance of a lower bound which can be broken by adding limited power to the communication model.

A Study on Key Success Factors in Multi-level Marketing Industry: Based on the Example of a Marketing Company

LIU, CHI-CHUN 29 July 2008 (has links)
Abstract From the multi-level marketing industry in Taiwan, this study chooses a multi-level marketing company which comprises the characteristics of the niche-based industry in Taiwan and has been established for more than a decade as its subject, aiming to analyze the key to the success of the said company. After the literature review and in-depth interviews with the industry in question, the findings are as follows: I. This study finds out that honesty, kindness and positive marketing concepts are the moral standards salespeople should possess; and the characteristic of being gregarious is regarded as special for the multi-level marketing industry. The operation of the multi-level marketing is based on the cooperation between the upper- and lower-level salespeople on a team basis, and those salespeople support, service, and help one another to accomplish everything, while the conventional business places emphasis on individual performances. Against the backdrop, the characteristics of the multi-level marketing salespeople are somewhat different from those of the conventional salespeople. II. The making of the multi-level marketing industry is that multi-level marketing salespeople have a better capability of providing services. Also, the capabilities of making recommendations, arranging organizational action competence, and drawing up plans for the organization are the factors used to evaluate the success of a multi-level marketing company. III. The interview with the case company done by this study proves the idea proposed by Porter (1985): the innovation of products or services contributes to the differentiation between an enterprise and its competitors, and the enterprise can acquire a better selling price; and the innovation of important techniques or approaches enables an enterprise to enhance efficiency, lower costs, and even form a differentiation. The said principle is applicable to other industries, and likewise to the multi-level marketing industry. Keywords: multi-level marketing, morals, service capability,

Design of The Rendezvous Mechanism In The Multi-Core AMBA System

Chang, Mu-Chi 06 August 2008 (has links)
In current chip multi-processors (CMPs), the on-chip network is a major factor affecting overall system performance. Different kinds of communication protocols vary from different communication architectures of current SOC designs. For example, the AMBA is master-slave architecture, which transacts and communicates the data of between the two CORE (Master) through the Memory (Slave). The architecture cost long time for load and store with memory. Hence, this paper design and implement a Rendezvous protocol on AMBA architecture, which is called Rendezvous of Advanced High performance Bus (RAHB), to let two processors can communicate with each other without memory reference overheads. The RAHB is compatible with the AHB architecture, and add Rendezvous communication protocol in the AMBA architecture to perform the direct transmission of data. Without referring the memory, the RAHB can improve the efficiency of communication in multi-core. For experimental evaluation, we evaluate the performance between RAHB and AHB, RAHB speedup (B/s) is average up to 50% for different data length and performance up 30% to 40% for executing test program.
